R33 Battery Going Flat After 2 Or 3 Days

[Boof R33]

tested amp drain when car is off at 0.95 amps is this normal the car is more track then show and has only minimal sound equipment std. speakers aftermarket deck. It has got a power fc and bosch 044 pump. what could be my problem. i have tried a new battery

any help greatly appreciated and yes i did search and could not find anything about amp draw

start pulling fuses until the draw goes away. that almost looks like a light is on somewhere. if you are working in the boot push the boot catch closed and retest.

normal draw is 20-50mA so 0.02 or 0.05A.

checked all lights pulled all fuses still no good

what kind of alarm do you have?

[Boof R33]

auto watch got all fuses out of it now just letting it sit for a day and see if any volts escape

[Carbon 34]

hate it when the volts excape.lol

bet its a bad backup battery in the siren ?? happens after about 2-3 years or more often if you don't drive often or deep cycle the main battery?

or stuck relay ? your sure nothing is wired to be on with the key off ? aftermarket stuff ??

battery drain how to check?

do i simply remove the -ve battery cable and use a test light to hook one end to battery -ve post and other end to -ve battery cable and see if test light glows?

[Chris Rogers]

similar idea. use a ammeter or multimeter that will measure current.

i think this might be the problem however i got all the kickpanel fuses out and its not loosing voltage just got to work out which one it is. car for last 2 year is old a weekender/ fortnight car

well that's easy then.

disconnect negative cable from your battery.

grab a multimeter and set the dial to read Amps - 10A.

clamp one of the multimeter leads to the negative terminal of the battery, and the other lead to the negative cable you disconnected.

Now the circuit is complete, and power is back on.

Your multimeter should be showing you the current drawn from your battery.

So with the car turned off (make sure interior light and boot light are off), start removing one fuse at a time, and check the meter each time to see if the current draw has dropped to acceptable levels. 0.05A or under.

Replace fuse, and pull the next one untill you find the one single fuse that causes the current reading to drop. whatever that fuse powers is the source of your problem.
